HEAT EXCHANGER TRAINING

APPARATUSMODEL: HE 158C

SOLTEQ®Equipment for Engineering Education & Research

THIS Heat Exchanger Training Apparatus (Model: HE 158C) is a bench type unit designed to allow

students to get familiarised with different kinds of heat exchangers and to collect the necessary experimental

data for the calculation of heat loss, heat transfer coefficient, log mean temperature difference, etc. Studentwill also be able to study the effect of flow rate on the heat transfer rate. Later, students may use this knowledge for

designing complex industrial heat exchangers.

The HE 158C is supplied with four types of heat

exchangers with two 50-L stainless steel sump tanks

as the source for the hot and cold water circuit. The hot

tank is fitted with a 11.5 kW immersion type heater which

is protected against possible over heating. Each tank

has a centrifugal pump to deliver the hot and cold water

to the heat exchangers. The pumps are somehow

protected from dry-run by level switch installed in each

of the sump tanks. A temperature sensor and

temperature controller are also provided to maintain a

constant desired temperature inside the hot water tank.

The unit is supplied with all necessary instruments to

measure the inlet and outlet temperatures of the hot

and cold water as well as the flow rates of the hot and

cold water and the pressure drops across the heat

exchangers. Piping and fittings are made of stainless

steel materials to prevent rust. The hot water and cold

water circuits are properly insulated to minimize heat

losses or heat gains between the tank and the heat

exchangers.
